How to Connect Your iPhone to iTunes on Your Computer

Connect your iPhone using a USB cable or Wi-Fi

To connect your iPhone to iTunes, you need either a USB cable plugged into your computer or a Wi-Fi network that both devices share. iTunes is Apple's media management program — it lets you back up your phone, sync music and videos, and manage your device settings from your computer. The USB cable method is faster and more reliable, but Wi-Fi works if you prefer not to plug in.

Before you start, make sure you have iTunes installed on your computer. If you're using a Mac with macOS Catalina or newer, the Finder app handles iPhone connections instead of iTunes. Windows users and older Mac users will use iTunes directly.

Key Takeaways

A USB cable is the most direct way to connect — plug it into your iPhone and your computer, then open iTunes or Finder.
Wi-Fi syncing requires you to set it up once with a cable, then your phone will connect wirelessly when both devices are on the same network.
On Mac computers running Catalina or newer, use Finder instead of iTunes to manage your iPhone.
Your computer will ask you to trust the connection the first time — tap "Trust" on your iPhone screen to proceed.
Once connected, you can back up your phone, sync media, update iOS, and manage storage from your computer.

Connect with a USB cable on Windows or older Mac

Plug the USB cable into the bottom of your iPhone and connect the other end to an available USB port on your computer. Windows users and Mac users with older operating systems will see iTunes open automatically, or you can open it manually from your Applications folder (Mac) or Start menu (Windows).

Your iPhone screen will show a prompt asking "Trust This Computer?" Tap Trust on your phone. If you don't see this prompt, unlock your iPhone and try again. Your computer may also ask for permission — click Continue or Allow to proceed.

Once trusted, your iPhone icon appears in iTunes at the top left of the window. Click it to see your device summary, backups, media sync options, and other settings. Your phone is now connected and ready to sync.

Connect with a USB cable on Mac with Finder

If you're using a Mac with macOS Catalina (released in 2019) or newer, Finder replaces iTunes for iPhone management. Plug your iPhone into your Mac with the USB cable. Open Finder from your dock or Applications folder.

In the Finder sidebar on the left, you'll see your iPhone listed under "Locations." Click your phone's name to open its management window. Your iPhone will show the same trust prompt — tap Trust on your phone screen. Once trusted, you can back up, sync media, and manage your device from Finder instead of iTunes.

Set up Wi-Fi syncing after the first cable connection

Wi-Fi syncing requires an initial USB cable connection to enable it. Once your iPhone is connected with the cable and trusted, open iTunes (Windows or older Mac) or Finder (newer Mac). Click your iPhone icon and look for a checkbox labeled "Sync with this iPhone over Wi-Fi" or "Show this iPhone when on Wi-Fi."

Check that box and click Apply or Done. Your phone will now connect to iTunes or Finder wirelessly whenever both devices are on the same Wi-Fi network and your computer is running. You can unplug the cable — the connection is now set up for the future.

Keep in mind that Wi-Fi syncing is slower than USB and works best when your computer is plugged in and your iPhone is charging. If syncing stalls or fails, plug in the USB cable to complete the sync, then return to Wi-Fi mode.

What to do if your iPhone doesn't appear in iTunes or Finder

If you plug in your iPhone and it doesn't show up, first check that the USB cable is fully inserted into both the phone and the computer. Try a different USB port on your computer — some ports deliver power only and won't transfer data. If you have a different USB cable available, test with that one, because cables wear out and stop working.

On your iPhone, tap Trust if the trust prompt appears. If it doesn't appear, unlock your iPhone and try unplugging and replugging the cable. On Windows, restart iTunes. On Mac, restart Finder or restart your computer entirely. If you're using an older iPhone or iPad, you may need to update iTunes to the latest version from Apple's website.

If your iPhone still doesn't appear after these steps, the cable or USB port may be damaged. Try connecting on a different computer if you have access to one — this tells you whether the problem is your phone or your computer.

Back up and sync your media once connected

Once your iPhone appears in iTunes or Finder, you can create a backup by clicking your device and selecting Back Up Now. A backup stores your photos, messages, settings, and app data on your computer so you can restore everything if something goes wrong with your phone.

To sync music, videos, or podcasts, click the Music, Movies, or Podcasts tab in iTunes or Finder. Check the box next to "Sync" and choose which items you want on your phone. Click Apply to transfer them. Syncing copies files from your computer to your iPhone — it doesn't move files the other direction, so your computer copy stays intact.

You can also update your iPhone's operating system (iOS) from this window. If an update is available, you'll see a button labeled Update. Click it to download and install the latest version. Keep your phone plugged in during the update — it usually takes 10 to 20 minutes.

Disconnect your iPhone safely

When you're done syncing or backing up, you can unplug your iPhone at any time — there's no "eject" step required like with external hard drives. If you set up Wi-Fi syncing, your phone will stay connected to your computer wirelessly until you turn off Wi-Fi, move out of range, or disable Wi-Fi syncing in iTunes or Finder.

If a sync is in progress when you unplug, wait for it to finish first. You'll see a progress bar in iTunes or Finder. Unplugging during a sync can interrupt the backup or transfer, though it rarely causes permanent damage.

Frequently Asked Questions

Do I need iTunes if I have a Mac?

If your Mac runs Catalina or newer (2019 or later), you use Finder instead of iTunes. Older Macs and all Windows computers use iTunes. You can check your Mac version by clicking the Apple menu and selecting "About This Mac."

Can I use any USB cable to connect my iPhone?

Any Apple USB cable designed for your iPhone model will work. Older iPhones use the 30-pin connector, iPhone 5 and newer use Lightning, and iPhone 15 and newer use USB-C. Third-party cables sometimes work but may not transfer data reliably — Apple's official cables are most dependable.

Why does my iPhone keep asking me to trust this computer?

This usually means the trust setting didn't save properly. Tap Trust again and wait a few seconds before unplugging. If it keeps asking every time you connect, try restarting both your iPhone and computer, then reconnect and trust again.

Will syncing delete music that's on my iPhone but not on my computer?

Yes — if you sync music and a song is on your phone but not in your iTunes library, syncing will remove it from your phone. Before syncing for the first time, make sure all the music you want to keep is in iTunes on your computer, or use Wi-Fi syncing cautiously until you're confident in your setup.

Can I connect my iPhone to multiple computers?

Yes, but syncing to a different computer will replace your existing sync. If you sync to Computer A, then sync to Computer B, the music and videos from Computer A will be removed. You can back up to multiple computers without this problem — backups don't replace each other.
